Obtained maps related to the dynamics of the SNR. Left: shocked ejecta velocity V_z from our Bayesian spectral study. The uncertainty (top left) only represents the statistical error. Middle: comparison for each region between the median of the velocity V_z in each region from the GMCA maps and the values obtained in this study with a Bayesian spectral fit. Right: Sig_6keV parameter, which corresponds to the spectral Gaussian smoothing applied to all the ejecta components (first color bar) equivalent to shocked ejecta velocity dispersion ∆V_z (second color bar).
